AI-Powered Educational Dictionary Database

I need an AI-assisted creation of a comprehensive English dictionary database for the Goldendict mobile app. The base will be Wikipedia's dictionary, enhanced by merging content from the Oxford Concise Dictionary, Cambridge Advanced Learners Dictionary, and Columbia Encyclopedia. The final product must be distinct enough to avoid copyright issues.

Key Requirements:
- Definitions
- Examples of usage
- Synonyms and antonyms
- Derivations
- Pronunciation

Ideal Skills and Experience:
- Proficiency in AI and data merging
- Strong understanding of linguistic databases
- Experience with Goldendict or similar mobile app integration
- Knowledge of copyright laws and content creation
